A Case of Uncontrolled Diabetes Complicated by Nonketotic Hyperglycemic Hemichorea

Abstract

Nonketotic hyperglycemic hemichorea (NHH) is a rare complication of uncontrolled Type II diabetes mellitus (T2DM). This report shares the case of a 53-year-old man from West Virginia presenting with an acute onset of hemichorea and a several-year history of uncontrolled T2DM. The patient's physical examination, laboratory, and radiologic findings indicated severe hyperglycemia and striatal hyper-density, leading to the diagnosis of NHH. NHH should be included in the differential diagnosis of patients with acute movement disorders, especially in West Virginia with its high rate of Type II diabetes.
